Page 5
Push-Button Programming Mode:
Programming mode is used to program the Analog Out output on the VSFM-002. There are two options for
the Analog Out output. The VSFM-002 can output an analog voltage based on either temperature or fan/pump
speed.
If you are not planning on using the Analog Out output, you do not need to program this feature.
• The default Analog Out output is temperature based.
• When the temperature option is selected, the Analog Out will output a
0-5 V (+/- 0.02 V) linear analog signal dependent on the temperature
sensor you have chosen (more information on page 11 and 12).
Program Button
• GM ECT/IAT/TFT, AEM ECT, and the Bosch IAT/ECT sensors:
• 0.02 V ≈ 1.4 Deg F
• 0-350 Deg F
• 0.00 V = 0 Deg F
• 5.00 V = 350 Deg F
• GM/AEM/Bosch/Sensata EGT Platinum RTD sensors:
• 0.02 V ≈ 5 Deg C (9.1 Deg F)
• 0-1275 Deg C
• 0.00 V = 0 Deg C (32 Deg F)
• 5.00 V = 1275 Deg C (2327 Deg F)
• When the speed option is selected, the Analog Out will output a 0-5 V (+/- 0.02 V) linear analog signal
dependent on the current speed (0-100%) of the fan/pump. Analog Out will output 0.00 V at 0%, and
Analog Out will output 5.00 V at 100%.
To enter Programming Mode:
• Ignition off (VSFM-002 power off)
x100
• Set all four 10 position switches to 0 and the 16 position switch
to 0. The “Start Temp” setting switches should be pointing to the
right, the “Max Output Temp” setting switches should be pointing
down, and the “Device Select” 16 position switch should be
pointing up. See illustration on the right for switch positions.
• Ignition on

Temperature Controlled PWM Mode:
To enter Temperature Controlled PWM Mode, DIP switch #3 must be in the DOWN position.
Device operation:
The Temperature Controlled PWM mode is controlled by temperature. The speed of the fan/pump will increase
linearly with input temperatures between Start Temp and Max Output Temp. When the input temperature is
less than Start Temp, the fan/pump will be off. When the input temperature is equal to Start Temp, the fan/
pump will operate at minimum speed. When the input temperature is greater than or equal to the Max Output
Temp, the fan/pump will operate at maximum speed.
When the Override Input is activated, the fan/pump will operate at maximum speed. If the VSFM-002
recognizes that a temperature sensor is not connected, the controller will go into failure mode. Failure mode
will cause the fan/pump to run at maximum speed.
Relay Output Wire - The relay control output will output a ground signal when the fan is operating at maximum
speed. The relay control output is intended to control a warning light or auxiliary device.
LED operation:
• Solid RED indicates that the fan/pump is off.
• Solid GREEN indicates that the input temperature is between Start Temp and Max Output Temp (fan/pump
operating range).
• Blinking GREEN indicates that the input temperature is greater than or equal to Max Output Temp (fan/
pump max speed).
• Blinking RED and GREEN indicates that the Override input in active (fan/pump max speed).
• Blinking RED indicates that Start Temp is greater than or equal to Max Output Temp, or there is no
temperature sensor connected to the VSFM-002.
Page 8
User Controlled Fan/Pump Speed % Mode:
To enter User Controlled Fan/Pump Speed % Mode, DIP switch #3 must be in the UP position.
Note - You will only need a temperature sensor in this mode if you are using Analog Out to output a 0-5 V
signal based on temperature. The temperature sensor does not control the speed of the fan.
Speed Control:
• 0% is off.
• 1% is minimum speed.
• 99% is controller output maximum speed.
• Actual speed percentage is +/- 1%.
Device operation:
The User Controlled Fan/Pump Speed % is controlled by user input. In this mode, the Start Temp dials function
as the Starting Speed %, and the Max Output Temp dials function as Input Activated Speed %. The conversion
from Temperature to Speed % is as follows: 10 Degrees in Temperature Controlled PWM Mode = 1%
in User Controlled Fan/Pump Speed % Mode. An EXAMPLE LABEL* for the USER CONTROLLED
FAN/PUMP SPEED % Mode is shown in the image below.

showing how the module operates when in the User Controlled Speed % Mode.
In the example shown above, the starting speed %
The Fan/Pump speed percentage pertains to the fan/pump device select chart (Table 2).
0% = Off Duty %
1% = Min Duty %
99% = Max Duty %
When the VSFM-002 is powered on, the fan/pump will begin to operate at the Starting Speed %. Once the
VSFM-002 Override Input is active, the fan/pump will operate at the Input Activated Speed %.
If you want the pump/fan off when the Override Input is not active, set Starting Speed % to 0. Then set Input
Activation Speed % to the desired activation speed %.
NOTE: Starting Speed % does not have to be less than Input Activation Speed % in this mode.
LED operation:
• Solid GREEN indicates Override Input activation is inactive.
• Solid RED indicates Override Input activation is active.

Installation:
1. Disconnect the negative battery terminal.
2. Connect the black wire of VSFM-002 too a suitable vehicle ground. Failure to fully secure the ground
wire to a vehicle ground source could result in malfunction of the module.
3. Connect the red wire to a switched and fused +12 volt DC source. A 5-10 amp fuse should be sufficient.
4. Connect the gray Relay Output wire to the ground side of the device you wish to control.
• A relay should be used if the relay control output will be controlling a device that pulls more than 0.75
amps.
5. Configure the DIP switch settings behind the back cover of the VSFM-002.
6. Connect the Purple and Brown Wire to a temperature sensor.
7. Connect the white wire to a desired activation source if using the Override Input.
8. Connect the PWM signal wire to the fan/pump you will be controlling (see Table 2 on page 7).
• If the fan/pump you are connecting to has an internal pull-up resistor, connect the yellow PWM Out,
Ground, to the PWM input on the fan/pump.
• If the fan/pump you are connecting to does not have an internal pull-up resistor, connect the orange
PWM Out, +12V, to the PWM input of the fan/pump.
9. Secure the VSFM-002 using the supplied hook and loop tape or using the supplied self-tapping screws.
10.Adjust the dials on the front of the VSFM-002 to desired settings.
11.Reconnect the negative battery terminal.
Additional Notes and Warnings:
• Changes to the switch settings must be done with the VSFM-002 powered off.
• The switch positions are only read on start up (initial device power up).
• The low Temperature Setting (Start Temp) must be less than the high Temperature Setting (Max Output
Temp) when in Temperature Controlled PWM Mode.
• The VSFM-002 will not work on fans/pumps that require more than 250 Hz or less than 1 Hz for the PWM
signal.
• Make sure that the VSFM-002 ground wire is properly secured to a vehicle ground. Failure to fully secure
the VSFM-002 ground wire to a vehicle ground source could cause the VSFM-002 to malfunction.
• Do NOT submerge the module in liquid or directly wash the unit with liquid of any type. The switches on
the VSFM-002 are sealed but are NOT rated for high pressure washing, use caution if power washing near
the VSFM-002 module.
• Do NOT mount the VSFM-002 directly on top of the engine or near the exhaust manifolds due to heat
concerns.
• Do NOT mount the VSFM-002 in the line of site of high temperature objects such as exhaust manifolds,
turbine housings, etc... If needed, install a heat shield in between the heat source and the module to
protect the plastic case.
• Do NOT install within 6” of nitrous solenoids or other devices with strong magnetic fields.
• Do NOT install near the spark plugs or the spark plug wires (or other potential strong sources of electrical
noise).
• LPE recommends the use of resistor type spark plugs and RFI (radio frequency interference) and EMI
(Electromagnetic Interference) suppression spark plug wires on all EFI engines and any vehicle that
has electronic control modules on board (including the VSFM-002). Failure to do so may result in erratic
operation of electronic device

Using the VSFM-002 to activate one or two fans or
pumps based on ECT sensor output
Using the wiring diagram below, the speed of the fan(s) is based off of temperature. The fan(s) will turn on
when the ECT sensor reads a temperature equal to the “Start temp.” The fan(s) will run at maximum speed
when the ECT sensor reads a temperature equal to or greater than “Max Output Temp.” (There is a linear
relationship between fan speed and the “Start Temp”/”Max Output Temp” window). If using a manual override
switch, a ground signal is sent to the “Override Input” when the override switch is activated. This will cause
the fan(s) to run at maximum speed. When the fan/pump is operating at maximum speed “Relay Output” is
active. “Relay Output” can be connected to an LED warning light or an auxiliary cooling fan.

*Some Brushless PWM controlled fans/pumps may require a switched power source. Without a switched power source,
the fan/pump may run at full speed or drain the battery when a pwm signal is not present (e.g. VSFM-002 is powered off ).
Other fans/pump do not require a switched power source, and will go into a low power mode when a pwm signal is not
present. Check your fan/pump documentation to determine if your fan/pump requires a switched power source.

APPENDIX A
Advanced Settings:
The advanced settings affect the Temperature Controlled PWM mode and the User Controlled Fan/Pump Speed
% Mode.
When DIP switch #4 and #5 ARE NOT positioned in the same direction, the Override Input logic
is reversed.
• Instead of the fan/pump operating at max speed (Temperature Controlled PWM Mode) or Input
Activation Speed % (User Controlled Fan/Pump Speed % Mode) when there is an Override Input
Activation signal present, the fan/pump will operate at full speed or Input Activation % when an
Override Input Activation signal is not present.
• The tables below show the corresponding outputs depending on the different input combinations.

APPENDIX B
SPAL Control Strategy:
SPAL has two different control strategies. If you do not know which SPAL fan “Device Select” option (page 7)
to choose, check the fan motor on the backside of the fan.
PLUS SERIES - Choose “Device Select” 1
NON PLUS SERIES - Choose “Device Select” 0
NOTE: SPAL specifies that a device using a SPAL control strategy to control a corresponding SPAL fan will not
void the factory warranty. The Lingenfelter Performance Engineering VSFM-002 conforms to SPAL’s control
strategies.
Page 15
Troubleshooting:
If you believe your device is not operating at the correct speed, check the following:
•
Verify that you have selected the correct device (Table 2, page 7).
•
Verify that you have selected the correct temperature sensor (Table 3 and 4, pages 11 and 12).
•
Verify that the VSFM-002 is operating in the correct mode (DIP switch #3, pages 8 and 9).
If the Override Input is not working correctly, check the following:
•
Verify that the Override Input signal is not activated when the VSFM-002 is powered on.
•
Verify that you are you using the correct Override Input signal (DIP switch #5, page 5).
